PROCESSING METHOD FOR DISMANTLED BODY SUCH AS RADIO-ACTIVELY CONTAMINATED EQUIPMENT AND ITS TRANSPORTATION CONTAINER

PURPOSE:To decontaminate a metallic material by injecting decontaminating liquid into the transportation container which contains the dismantled body such as the radioactively contaminated equipment and carrying the container in processing facilities,and cleaning the dismantled body in the transportation container after the waste liquid of the decontaminating liquid is discharged. CONSTITUTION:The radioactively dismantled equipment which is removed from atomic power utilizing facilities is processed by cutting, etc., in a dismantling process 1 and stored divisionally in transportation containers by proper quantities in a transportation container storing process 2. Then each transportation container containing the dismantled body is reduced in pressure in a vacuum sucking process 18 and the decontaminating liquid is charged suctionally in a decontaminating liquid injecting process 19. In an in-plant transporting process 4, the container is transported to processing facilities 51 together with the decontaminating liquid and then passed through a decontaminating liquid discharging process 20 and a cleaning process 21 right after reaching the processing facilities 51, and the dismantled body is taken out of the container, which is reused. The dismantled body is stored after a general disposal process 15, reutilization process 16, or radioactivity-level-classified processing process 17 according to the residual radioactivity level of a radioactivity measuring and discriminating process 14.
